以NACA0015标准机翼为原型，在机翼前缘增加等间距的突起，并将其与随自由液面作升沉运动的浮子用铰链连接，设计出新型震荡水翼辅助推进装置。把新型装置安装于大型集装箱船（KCS）船首两侧，探索改善船舶推进性能的新形式。首先建立三维数值波浪水池，运用直接输入法进行数值造波，然后综合运用滑移网格技术与重叠网格技术模拟KCS加装新型震荡水翼辅助推进装置前后在规则波中的航行状态。最后将得到的数据进行对比分析，探究新型震荡水翼应用于大型集装箱船的辅助推进性能。
Taking NACA0015 standard wing as the prototype, a new type of oscillating hydrofoil auxiliary propulsion device is designed by adding equidistant protrusions on the leading edge of the wing and combining them with the float that heaves with the free surface. The new device is installed in the bow of large container ship (KCS) to explore a new way to improve the propulsion performance of the ship. Firstly, a three-dimensional numerical wave tank is established, and the direct input method is used for numerical wave making. Then, the sliding grid technology and overlapping grid technology are comprehensively used to simulate the navigation state of KCS in regular waves before and after the installation of the new oscillating hydrofoil auxiliary propulsion device. Finally, the obtained data are compared and analyzed to explore the auxiliary propulsion performance of the new oscillating hydrofoil applied to large container ships.
